Don is right of course. If you want a mag loop to actually act like an
antenna, it MUST be exactly resonant on your transmit frequency ...
period. No antenna "tuners," which have never "tuned an antenna"
anyway. Bypass the KAT2/KAT100 or whatever. Tune the mag loop cap to
1.0:1 ... not 1.5:1 or "close" ... 1.0:1. The K2 will tell you this.
That's all you do.
100W into a small mag loop probably exceeds it's ratings by close to an
order of magnitude, and please don't do it if I'm sitting next to it.
:-) These are QRP field antennas.

Dave and all,
You only have to put the tuner into Calibrate. For the KAT100 it is ATU
CAL.
The TUNE button will then simply put out a carrier (the KAT100 will not
tune, but is effectively bypassed). With the KPA100, that power will be
limited to 20 watts or if the Power Knob is set lower than 20 watts, it
will put out a carrier at the set power. If it is significantly higher
than that, the KPA100 wattmeter has a problem.

Hello, Brian.
I've read your post and the replies and figure I maybe read what you said
incorrectly, but you did say:
Then use the TUNE button on the K2 to tune the loop to resonance, then
operate.
You can't use the K2's antenna tuner to tune a loop to resonance. That's
not how they work.
